Touch automatic control and remote control device for cantilever tunneling machine

Abstract

The invention discloses a touch automatic control and remote control device for a cantilever tunneling machine. The device comprises a tunneling machine comprehensive protector, a control transformer, a controller, a methane sensor, an electric control box button, an explosion-proof electric bell, a motor, a current transformer and an explosion-proof remote control device, wherein the tunneling machine comprehensive protector, the control transformer, the methane sensor, the electric control box button, the explosion-proof electric bell, the motor and the current transformer are connected with the controller; the motor comprises an oil pump motor, a cutting motor, a second transportation motor and an anchor rod motor; the oil pump motor, the control transformer and the current transformer are connected with the tunneling machine comprehensive protector; the control transformer is connected with an illuminating lamp; the controller is an employment pass eligibility certificate (EPEC) dedicated controller; and the explosion-proof remote control device communicates with an industrial touch screen through a controller area network (CAN) bus. An electric control system of the cantilever tunneling machine is subjected to optimal design by an EPEC dedicated controller and industrial touch screen control technology, automatic control and remote control operation can be realized, and the device has high anti-seismic performance and reliability and is reliably operated.

Description

technical field [0001] The invention relates to a control device for a cantilever type roadheader, in particular to a touch-type automatic control and remote control device for a cantilever type roadheader. Background technique [0002] The cantilever roadheader is an indispensable large-scale underground mechanical equipment for safe and efficient production in the coal industry. It can realize continuous cutting, loading and transportation. The electric control system of the current cantilever roadheader adopts the PLC control system. The PLC control system monitors and protects the undervoltage, overvoltage, overload, overcurrent of each motor, and the leakage lock of the motor and its cables, and has a low voltage Leakage and gas monitoring and protection functions, the comprehensive protector is also an important part of the PLC control system, it communicates with the LCD screen on the operation box, and displays the voltage when the system is working normally, the loa...

AI Technical Summary

Problems solved by technology

However, the PLC control system has the disadvantages of low protection level and inconvenient disassembly and assembly, and the realization of the protection function requires a special protector for the cantilever roadheader. The man-machine interface uses a text display, and the text display can only display 2~ 4 lines of content
